3 Claims.

My present invention relates to an improved heating apparatus and more particularly such heating apparatus wherein air is heated by convection in contact with tubes containing hot water. The invention also includes means for supplying Water from a reservoir in which preliminary heating is accomplished.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention according to the best mode I have thus far devised but it will be understood that various changes and alterations may be made in the exemplified structure Within the scope of the appended claims.

In the drawings- Figure l is a top plan View of the heater of my invention.

Figure 2 is a vertical sectional View thereof taken at line 2-2 of Figure l.

Figure 3 is a horizontal sectional view taken at line 3 3 of Figure 2 and Figure 4 is a vertical sectional view at line 4--4 of Figure 1.

Referring now to the drawings in detail, I have illustrated the heater of my invention embodying a cylindrical casing 2 with the exterior thermometer 3, and formed with a closed top 4 and a closed bottom fi with the drain l' therein. rihe legs i support the cylinder 2 above the burner iii.

Within the cylinder I provide a horizontal partition l2 to which are attached vertical, spaced walls lil and it forming a central chamber I3 in the casing, about which is located the U-shaped water jacket 2t). A vertical Wall 22 divides the central chamber from the entrance chamber which is fashioned with a bottom 24 and top 2E.

A 1rower tank or reservoir 3@ is positioned belov7 the bottom of the entrance chamber.

The air tubes 3E of suitable material and formed to desired shape, as shown, connect the chamber 35i with the chamber 3d and air from the blower 35 and its ian 355 is forced into the chamber :it through the tubes 532 into the chamber 3&3 and out through the air outlet 3l.

The water tubes 38 permit the passage of water through. the top 2E and bottom 2t of the entrance chamber from the water inlet En? and the water after iiowing downwardly through said pipes is stored in the reservoir Sil.

An outlet pipe itl `from the reservoir 3!) is provided with a tap or faucet t2 and the vertical pipe lll permits the gravity flow of water upwards therein to the pump having he opposite oneway ball valves 5B and 52. The pump when operated by the handle t9 will liit the water in the pipe M from the reservoir 30 through the valves and thence through the inlet pipe 53 to the water chamber As the water in the water jacket 20 is heated from the burner, the heat will be transmitted through the wall of the reservoir to the water therein, so that the water added to the jacket from the reservoir will have received a preliminary heat and will not eiect a cooling action on the air passing through the air tubes 32.

A steam relief valve 5i will permit the escape of any steam in the water jacket should the pressure rise to a predetermined level.

In operation, the water in the jacket will be heated as desired by the burner lil, and water may be added thereto by the pump from the reservoir as is necessary. Air under pressure from the blower will be forced through the air tubes and the air will be heated by convection during its passage therethrough.

The air so heated will be exhausted through the outlet 3l and may be recirculated if desirable. The water in the jacket may be heated to a constant temperature, and hot water for washing or similar purposes will be readily available through the tap 42.

The heater of my invention is compact in construction and eiiicient in operation, and due to the manner of construction is portable and may be placed wherever desired. A constant water supply from outside is not necessary as the evaporation of water will be minimized inasmuch as the water jacket is sealed except for the relief valve permitting the escape of steam under too high pressure.

The air passing rst into the chamber 33 and through the pipes 32 Will be permitted to expand and circulate through the central chamber I8 and the air will then leave the chamber I8 for passage through the pipes 32 to the chamber 34 and thence to exhaust.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. An air heater comprising a cylindrical casing having a closed top and bottom, interior vertically disposed parallel walls, a bottom portion connecting the lower ends of said walls to form a central air chamber, said walls and said casing forming a water jacket about said central air chamber, horizontal partitions in said Water jacket below the closed top of said casing, forming two oppositely disposed air chambers, air tubes carried by one of said partitions and one of said walls and communicating with a blower connected to the chamber formed by said latter means for supplying pre-heated water to the wa-y ter jacket from the reservoir comprises a pump connected to said water jacket and said reservoir.

3. The invention as in claim 1 wherein a reservoir for supplying pre-heated water is formed in said casing within said water jacket, a pipe connecting the reservoir with the water jacket, a pump interpolated in the pipe, and valve means in the pipe on both sides of the pump permitting one-way passage of water therethrough.
